Northwood took over from the Key Place as our letting agent about half way through our tenancy. They were pretty reasonable and fair throughout their time. I would give 5 stars but it took several weeks to resolve a washing machine that needed replacing and a boiler that needed fixing (two or three times an engineer came round without keys when we told them no one was home and he would need to pick up keys from them). It also took several weeks to receive our check out letter after we had to prompt them a few times. However, the rest of the time they were reasonable and fair and didn't overcharge us for cleaning fees like I hear Southside do.
